medium Nessus Plugin ID 344315

Synopsis

The remote host is affected by a denial of service vulnerability.

Description

The version of Kibana installed on the remote host is 8.x prior to 8.19.17, or 9.0.x prior to 9.3.0. It is, therefore, affected by a vulnerability as referenced in the ESA-2026-31 advisory.

 - Allocation of Resources Without Limits or Throttling (CWE-770) in Kibana can lead to a denial of service via Excessive Allocation (CAPEC-130). An authenticated user with low-level permissions could submit a specially crafted request that causes excessive resource consumption, which may render Kibana unavailable.
 (CVE-2026-33465)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update to Kibana version 8.19.17, 9.3.0 or later.
